Starting today, North American PSN customers can grab one (or some) of a handful of Final Fantasy titles for half their price. As a part of Final Fantasy's 25th anniversary, the North American PlayStation Store is discounting several PSP titles and PSone Classics for the next two weeks, including the following:

PSone Classics:

Final Fantasy

Final Fantasy II

Final Fantasy V

Final Fantasy VI

Final Fantasy VII

Final Fantasy VIII

Final Fantasy IX

PSP games:

Dissidia: Final Fantasy

Dissidia 012[duodecim] Final Fantasy

Dissidia Duodecim Prologus

Final Fantasy IV: The Complete Collection

Final Fantasy Tactics: War of the Lions.

It's a shame that Crisis Core: Final Fantasy VII isn't on PSN. Interestingly, the sale also apparently omits Final Fantasy III (PSP) and Final Fantasy Tactics (PSone Classic).
